So as the subject suggest I have some questions about the product.

First, how long does any object need to be exposed/soaked for it to be effective of its full potential?

Second, how long does an unmixed/unused open concentrate last? Is there a expiration date via some code on the bottle that can be deciphered?

Third well I found my answer on there faq section so I will post it here for others - how long should you keep a mixed product before replacement? Daily when used with submerged items. Additionally any time it is mixed incorrectly or has otherwise been contaminated.
